Solar stocks, the market's top-rated group out of the 197 industries tracked by IBD, recorded some outsized, heavy-volume gains.

SunPower (SPWR) gapped up and bolted 11% after announcing a buyout. The company bought Greenbiotics, a California-based company which makes cleaning products for solar panels. The cash deal, for an undisclosed sum, is immediately accretive to results. SunPower is extended from a bounce off its 10-week moving average.

SolarCity (SCTY) also screamed ahead 11% after announcing an offering of $54 million of asset-backed notes. Canadian Solar (CSIQ) and Trina Solar (TSL) climbed 12% and 9%, respectively.

On the downside, discount European carrier Ryanair (RYAAY) gapped down and swooned 9% in frantic volume after the company slashed its profit guidance for the second time in two months.

In its half-year results release, Ryanair said that net profit for the fiscal year ending in March could fall to $675 million-$702.5 million vs. its earlier outlook of $769.5 million-$810 million given in September. Ryanair cited the weak European economy and rising competition.

The stock had shaped a 15-week cup-with-handle base with a one-day high-volume reversal marking the pattern's bottom. But Monday's slide makes rubble of that base-building attempt.
